DRAW ER-EQUALIZER.

SPECIFICATION forming part of Letters Patent No. 629,698, dated July 25,1899.

Application filed February 7,1899. Serial l lo. 704F778. (N0 model.) i

To all whom it may concern.-

Be it known that I, LUDVIO M. MILLER, a citizen of the United States,residing at VVinneconne, in the county of Winnebago and State ofWisconsin, have invented new and useful Improvements inDrawer-Equalizers, -of which the following is a specification.

This invention relates to certain new and useful improvements indrawer-equalizers, the object-of the improvement being to provide anattachment for drawers which when .applied thereto and to the drawerframe or casing will secure an even and regular sliding movement of thedrawer parallel to its frame and prevent the drawer sagging when movedpartially out of the frame, also to provide a stop or means for limitingthe outward movement of the drawer, and at the same time 'to generallyimprove a device of this charactor.

The invention consists in the construction and combination of the partswhich make up the drawer-equalizer, whereby a plurality ofvertically-disposed and coacting arms are so constructed, organized, andapplied to the drawer and its frame as to insure an easy slidingmovement of the drawer irrespective of its load or the pull which may beapplied thereto, the construction of the arms and means for securingparallelism of movement, holding the arms in true vertical alinement,preventing the drawer sagging or rocking in the frame when-opened orclosed, also preventing the drawer being pulled out of its frame, aswill be hereinafter set forth, and specifically pointed out in theclaims.

In the accompanying drawings, which illustrate the construction of myinvention and the application thereof, Figure 1 isa sectional view of adrawer-frame, showing the-drawerequalizer applied thereto,theattaching-plates being shown in section. Figs. 2and3 are detailperspective views of the equalizing-arms.

Referring to the drawings, A'indicates a drawer frame or case which isadapted to receive a drawer B. The drawer-frame may be of the simplesttype and has the usual guidestrips a, upon which the drawer slides, thedrawer being of slightly less depth than the frame. The equalizer isapplied to the center of the drawer and drawer-frame, and the I allyattached to plates the ends of which are bent at right angles with thevertical portions thereof, which are bolted or otherwise attached to thedrawer and its frame. The back plate 0, whichis secured to the frame A,has its upper and lower ends bent at right angles, so as to extendforward, and these bent portions have therethrough apertures for-thereception of stud-pins c c, which project from the ends of arms D D, soas to maintain said arms in swinging engagement with the back plate 0and in vertical planes, so that said arms will swing horizontally. Theouter ends of the arms D D are spread or bifurcated, so as to provideupper and lower members the ends of which are rounded or expandedhorizontally to provide a larger area of bearing-surface against theflat edges of the arms E, which they overlie, the arms E-havingstud-pins e, which pass through apertures in the arms D, and adjacent tosaid stud-pins are offset or projecting portions e, which when they abutagainst the ends of the arms D D limit theswinging or pivotal movementthereof, and thus provide means for limiting the outward movement of thedrawer. The front ends of the arms E E are provided with stud-pins 6which engage with perforations in the horizontal portions of the frontplate F, and the stud-pins are in alinement with those in engagementwith the back plate 0. Formed integral with the front ends of the armsE, so as to project horizontally therefrom, are sectors E, whichmeshwith each other and secure uniformity of movement of the arms E and D.Said sectors also bearing upon the horizontal portion of the plate Fprovide a large bearing-Sn rface and prevent any rocking movement of thearm E.

The whole construction of the device has in view to provide the jointswith the largest possible area of bearing-surface between the parts, sothat the arms when expanded or contraeted will move inline with eachother, so

that when the plates are properly secured tothe drawer and frame themovement of the drawer will be directly outward and any sagging ortilting of the drawer will be prevented.

lVit-h an equalizer thus constructed there are but single points ofcontact or attachment of the equalizer with the drawer-frame and ends ofthe arms of the equalizer are pivotdrawer, andwhen one of the-plates issecured in place that determines the position of the otherplate, and thearms being flat and vertically disposed occupy but little space rear ofthe drawer when it is closed, and the sectors insure an equal movementof the arms.

Having thus described my invention, what I claim as new, and desire tosecn re by Letters Patent, is-

1. The combination with a drawer and its frame, of plates attached tothe drawer and frame, arms pivotally connected to each other and to theplates, one pair of the arms having intermeshing sectors at one end andat the other end lugs or projections, the lugs being for the purpose oflimiting the movement of the arms in one direction, substantially as setforth.

2; The combination with a drawer and a drawer-frame, of plates attachedto the drawer and drawer-frame, said plates having horizontal portions,arms pivotally connected to the horizontal portions of the plates at oneend and to each other at the opposite ends, one pair of the arms havingat their adjacent ends intermeshing sectors and at their outer ends lugswhich are adapted to engage with the arms which are pivotally attachedto the plate secured to thedra wer-frame, substantially as shown and forthe purpose set forth.

3. The combination with a drawer and drawer-frame, of plates centrallyattached to the drawer and drawer-frame, arms pivotally attached to theplates, one pair of the arms having at one end at right angles to thevertical plane thereof and of the pivots intermeshing sectors and at theother end flat bearing-surfaces from which project pins, lugs formed onsaid arms adjacent to the pins, and arms pivotally connected to theplate attached to the drawer-frame and to the outer ends of the armshaving the sectors so as to be engaged by the lugs on the latter arms,substantially as shown and for the purpose set forth.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
